1. A base station antenna system comprising:
a beamforming radio having a plurality of radio signal ports including first and second radio signal ports; and
an antenna array including rows and columns of dual-polarized radiating elements, wherein the antenna array has a vertical stack of sub-arrays, wherein each sub-array comprises at least one row of the dual-polarized radiating elements of the antenna array, wherein each sub-array comprises a plurality of sub-columns of dual-polarized radiating elements, and wherein each sub-column comprises at least one respective dual-polarized radiating element of a column,
wherein the first radio signal port is coupled to first and second sub-columns of a first of the sub-arrays, and wherein the first radio signal port is free of coupling with a third sub-column of the first of the sub-arrays that is between the first and second sub-columns of the first of the sub-arrays, and
wherein the second radio signal port is coupled to first and second sub-columns of a second of the sub-arrays, and wherein the radio signal port is free of coupling with a third sub-column of the second of the sub-arrays that is between the first and second sub-columns of the second of the sub-arrays.
